Out of the five missions launched by the Government, the Aardram mission is primarily focussed to improve Primary Health Care to provide standard health care facilities to people at grassroots. This initiative is complemented by strategic investment for the improvement of infrastructure in secondary and tertiary health care institutions to provide quality health care services. I am happy to note that the Department of Health is also taking initiatives to bring standardization in treatment for various disciplines like Cardiology, Critical care, Diabetes Mellitus, Cancer Care, etc. It is a noteworthy initiative to improve the qualitative aspects of the health service delivery. I appreciate the efforts taken by the experts from Government sector and private sector from Kerala and also the subject experts from outside the state. I am hopeful that the introduction of standard guidelines for diagnosis and treatment will ensure better quality and consistency in health care. I wish all the success to this endeavour. Pinarayi Vijayan Chief Minister 9 Message 11 Foreword Patient care has moved away from management by an individual based on personal knowledge and skill to an evidence based, team managed operation. Decisions are reviewed more rigorously post facto and their alignment verified with standard practice. With the mode of payment for care moving from out of pocket payments to third party payers there will be a demand for rigorous documentation and evidence of having conformed to standard practice. When analysis of big data and machine learning becomes the norm it will require a standard set of procedures to act as the baseline from which to measure deviations and differences in impact. To meet the requirement of these developments in the field of medicine, it is necessary to have explicit, objectively verifiable set of standard operating procedures. They have to be prepared based on international guidelines with the highest acceptance, but have to be modified to suit local knowledge and practice, so that there is local ownership. Government of Kerala has been trying to get the guidelines prepared for some time now. I would like to thank and congratulate Dr. Sreekumari, Joint Director of Medical Education and Dr. T.K.Suma, Professor of Medicine, T.D. Medical College, Alappuzha who took on the task of preparing standard treatment guidelines and completed it through a long, consultative process. I also thank the conveners of the different thematic groups who coordinated the work in their field as well as the innumerable number of participants, in government and private sector, who contributed their effort and knowledge to improve the guidelines. Professional associations have also contributed in their fields. Their efforts have resulted in a product they and Kerala can be proud of. Treatment guidelines cannot be static if they are to remain relevant. They must be updated based on new knowledge and the 13 experience of treatment based on these guidelines. To do this the group which prepared the guidelines has to remain active and have a system for collecting data on the results of practice based on these guidelines. I hope such an activity is institutionalised and periodic revisions of the guidelines are prepared and published. I wish that these guidelines contribute to raising the quality of patient care in Kerala.
